The fans all seem to be blowing cool air.
According to the bios, the CPU is at 42c and the Motherboard is 40c.
According the ATI Catalyst software, the video card is 71c, but the card has always been around that temperature.

I've got six fans as wide as the drive bays, three on the front, two on the back and one on the side.
And then a 120mm fan on the top of the case. None of them feels hot.
